You guys must have seen something in Maggie I didn't. For me, her function was to make me not feel bad when Rachel dies. I can't believe I'm saying this but Katie. I disliked Maggie so much in TDK, she's a big negative in a film for me.

We just saw Maggie acting , in comparison to what Katie does. It's easy to choose.

As another user said , Maggie brought believability to the role. I could see her like an assistant DA.
